2 Claims; (01.132-42) This invention relates to" an improvedhollow hair curler.

It is an objectofthis invention to=providea hollow hair curler of the'kind to be more-partied larly described hereinafter" to permit the free movement of air" within the curl to' be effected whereby the wet hair may be rapidly dried.

Another objectof this invention is to provide a hair curler of this-kind which may be removed from hair-in a semi-dry condition without dis turbing the designof the-curlandpermit's pinning part, the hair canbe left'in the curled conditionand allowed to dry with or without specifically directed warm air orthe use of a: drier.

Still another object of this invention is to'provide a curler of this kind having elongated perforations running lengthwise of the" bodyto present a flat or straight line along" the curler,- with this type ofperforation, the hair is" not permitted to fit down in the open" spaces as-would be permitted'with roundopenings; therefore the hair is held from becoming-locked orfitted'in the openings and will slide and come free of" the curler without any markings on the wrapped-curl;

A further object is to providea curler highly desirable and" advantageous in the process of permanent-waving, as in a cold wave, since it permits the inner drying-or curing to't'ake place from within'the curler, as well as from the out side andpermits inner saturation of' the" curl when fixing solutions are employed.

A still further object of'this" invention is to provide a curler which is" advantageous andde sirable for permanent waving when chemical heat pads are employed as the. curler. is hollow and perforated and permitstheapplication of inner heating of the .curl by chemicalor'mechanical means.

To the foregoing obiects,.and..others which may hereinafter more'fully appear, the invention consistsof the novel constructiom combinationiand arrangement of. parts, as'willbem' ore specifically referred to andillustrated-in the accompanying drawings, but it is to be understood that changes, variations, and modifications may be resorted to which fall within the-scope or the invention as claimed.

In the drawing:

Figure 1 is a side elevation of s, hair curler constructed according to an embodiment of my invention.

2 Figure 2 is a vertical'section of the curler shown in Figure-1.

Figure 3' is a transverse section taken on the line 3-3 of Figure l. Figure l is a transverse Section" taken on the line i -40f Figure "1. Figure 5 is a side elevation of a modified form of this invention. Figure fi is a- .transversesection taken on the line-6--B'of Figure 5.

Figure 7 is a side elevation of thelower member of another'modified form. Referring to the drawing, the numeral I 0 desig= natesgenerally a hair curler constructed: according-to an embodiment of this invention which is'formed of metal; plastic or other suitable material for providing'a hollow. body H open at both ends thereof. The hollow body' II is formed of an upper section 12: and a lower section. which are slidably connected together atone end thereof. Eachof the sections'n and Maresubstantiaily frusto-conical in configuration and formed with thin-walls. Thenarrowr end-asv l5of the lower bodyseetion l4 issub'stantially cylindrical in shape "and the lower end I6 of the upper section I2 is also cylindrical for telescoping engage-:- ment' over the cylindrical end 15 of the lower section I I; The side walls of the body H are formed with elongatedopeningsas 11 therein which are disposed in substantial axialalignment along the length thereof; Theopenings' I! are elongated'in the-direction of the lengthof the curler Hi to provide'for the admission of drying air through the walls whereby hair'whichiis curledvorr the device may "be exposed to vdrying air interiorly' of the curl formedfthereon. The openings! 1' are-formed in'thewalls oftherbody' It by strikingvanes I8 inwardly. Thervanesrinthis manner'are formed integral with the walls of the device and are adapted to be struck inwardly to provide 1. -shapedvane5rof this? kind which'zhave an axial arm I9 and a transversearm 20. The trans= verse arm '20 *connectsthe vertical arm I91 off'the vane. to the wall andthe end of the' vane closest to the end of the body His leftxfree: In" this mannerthe air is permitted to enter the ends ofithebody H and to be deflected inwardly and radially 'of'the'curler HI and of the curl of hair disposed thereon;

As noted above the: cylindrical section "of the lower body portion I4 is adapted to be telescoped into the cylindrical section of the upper section I2. For holding the two body portions 1'2 and I4 against rotation relative to each other, I have provided guide means which are formed integral with the cylindrical portions of the bodies for interengagement between the cylindrical sections. The cylindrical section l5 of the lower body portion I4 is formed with outwardly bent guide beads 2| which terminate at the upper or free end of the cylindrical section. Guide beads 22 are bent from the lower end of the cylindrical section [6 of the upper portion l2 and the beads 2| are adapted to be slidingly engaged within the grooves or channels 22. In this manner a sliding engagement of the two body sections is obtained and the body sections when engaged are held against rotation relative to each other.

For securing the two body sections I2 and M together I have provided a resilient flexible connecting member 24. The connecting member 24 may be made of rubber or plastic or other suitable flexible material and is fixed at one end to the divergent end of one of the body sections as the body section l2; -A radially extending arm as 25 is formed integral with the divergent open end of the body section l2. The arm 25 may lie substantially flush with the plane of the open end of the curler or may be spaced inwardly therefrom. An opening 26 is provided in the arm 25 and the end of the band 24 is fixed into th opening 26. r A spring clip as 21 is carried by the other end of the resilient connecting member 24. c1ip'21 is formed of a short length of metal which is bent into opposed U-shaped members-each having a pair of substantially parallel arms 28 connected together by a common bight portion 29. The free ends of the arms 28 are disposed in divergent relation one to the other to provide an entrance channel into the clip 21. The flexible member 24 is fixed in an opening in the bight 29 for securing the clip 21 thereto. The length of the resilient connecting member v24 is substantially the same as the length of the full body so that when a curl of hair is disposed about the body the connecting member 24 will be disposed outwardly of the curl and will be tensioned when the clip 21 is engaged with the divergent end of the other body section l4. As one of the U- shaped members is engaged as a clip, the opposite member is disposed as a handle or finger grip for the clip 21.

In the use and operation of this curler ID the two body sections I2 and I4 are slidably connected together by engaging the cylindrical sections l5 and I6 together and slidingly engaging the bead 2| into the guide channel 22. The hair to be curled is wrapped about the body and the flexible member 24 is stretched over the curl and the clip 2! is engaged with the free divergent end of the lower body section l4. In this manner the hair is securely mounted on the curler l and the two sections l2 and I4 of the curler are secured together.

In Figures and 6 there is disclosed a modified form of curler 30 formed of body sections 3| and 32'whichare formed in substantially the same manner as the body sections l2 and I4 described above. In the curler 30 the cylindrical sections 34 and 35 are slidably connected together and no means is provided for restraining the rotation of the two body sections one relative to the other. A connecting member 36 is fixed at one end to one of the body sections as 3| in the same man- The spring ner as described for the body section l2 and the connecting member 24. The same type of clip as 21 may be used on the flexible member 36 for securing the body sections 3| and 32 together. In the preferred form of the modified body section the connecting cylindrical sections 34 and 35 may be slightly frusto-conical to provide for a secure connection therebetween, the frusto-conical formation of the sections 34 and 35 being opposed or opposite from the formation of the main body section to which the cylinder is attached. In other words, the convergent end of the section 34 would be connected to the convergent end of the body section 3|.

The convergency of the connecting sections 34 and 35 would be ve'ry'small so that the two sections 34 and 35 may be slidably connected together upon the exertion of suitable force for sliding the divergent end of the section 35 into the divergent end of the section 34.

-The size of theopenings in the walls of the curlers may be varied within the scope of this invention and are preferably long and narrow as shown in Figure 7 of the drawings. In Figure 7, the openings Ha of the curler Illa are relatively narrow and certain of the axially related openings are ofiset from adjacent openings. It will be understood ,that the size, number, and relative arrangement of the openings I'Ia may be altered as found most desirable. It is contemplated also that some curlers will be made without vanes, as vanes l9, and others with a smaller number of vanes.

I claim:

1. An improved hair curler comprising a pair of open ended hollow tubular members, means slidably connecting said members together in axial alignment, elongated instruck tongues on said members along the length thereof defining perforated walls and axially disposed guide vanes therein, and a resilient connecting member engaging the remote ends of said tubular members for securing said members together and for securing a curl of hair thereon.

2. An improved hair curler comprising a pair of open ended hollow tubular members, means slidably connecting said members together in axial alignment, elongated instruck tongues on said members alongthe length thereof defining perforated walls and axially disposed guide vanes therein, a resilient connecting member engaging the remote ends of said tubular members for securing said members together and for securing a curl of hair thereon, and correlated interengaging guide means on the adjacent ends of said tubular members restraining said tubular members against-relative rotation one to the other.
